STICKING TO IT

Chew on this: Gum not only freshens breath, it also may help control weight, reduce stress and improve concentration.At least that's what the Wm. Wrigley Jr. Co. hopes to prove with the launch of the Wrigley Science Institute, which will support at least 10 studies on these topics this year alone.The creation of the institute comes at a time when gum is getting a shot in the arm in other ways, thanks
